Bani et al (2013) outlined that their DOAS traverses did not cover the entire plume's cross-section and thus probably underestimated the actual SO 2 emission rate.…”

“…Syn-eruptive emissions in Indonesia were determined for only a few events, from either space-borne sensing or the petrologic method (see Pfeffer, 2007, for an updated list), but the total (passive + eruptive) SO 2 budget does not results better constrained (0.48-3.8 Tg/yr; Pfeffer, 2007) than that for only passive emissions. This paucity of information has persisted until today (see Shinohara, 2013), even though a recent work by Bani et al (2013) provided the first SO 2 flux datum for Papandayan and further data for Bromo volcanoes in Java.…”

“…1c) and occasional eruptions (the last one in January-March 2011;GVP, 2012). This volcano has been studied on a few rare occasions from the ground for its SO 2 emission and considered to be a small emitter (Andres and Kasgnoc, 1998;Bani et al, 2013). However, satellite records in 2011-2013 have revealed that Bromo, in tandem with nearby Semeru volcano (Fig.…”

The composition and fluxes of volcanic gases released by persistent open-vent degassing at Bromo Volcano, east Java (Indonesia), were characterised in September 2014 from both in-situ Multi-GAS analysis and remote spectroscopic (dual UV camera) measurements of volcanic plume emissions. Our results demonstrate that Bromo volcanic gas is water-rich (H 2 O/SO 2 ratios of 56-160) and has CO 2 /SO 2 (4.1 ± 0.7) and CO 2 /S tot (3.2 ± 0.7) ratios within the compositional range of other high-temperature magma-derived gases in Indonesia. H 2 /H 2 O and H 2 S/SO 2 ratios constrain a magmatic gas source with minimal temperature of~700°C and oxygen fugacity of 10 , which is ten times higher than reported from few previous studies. Our results indicate that Bromo ranks amongst the strongest sources of quiescent volcanic SO 2 emission measured to date in Indonesia, being comparable to Merapi volcano in central Java. By combining our results for the gas composition with the SO 2 plume flux, we assess for the first time the fluxes of H 2 O (4725 ± 2292 t d ) and H 2 (1.1 ± 0.8) from Bromo. Our study thus contributes a new piece of information to the still limited data base for volcanic gas emissions in Indonesia, and confirms that much remain to be done to fully assess the contribution of this very active arc region to global volcanic gas fluxes.

Multimethod Approach to the Study of Recent Volcanic Ashes from Tengger Volcanic Complex, Eastern Java, Indonesia

et al. 2017

Volcanic ash is a volcanic product with a wide distribution that can be used as a geological marker. In volcanic regions such as Indonesia, the identification of the sources of volcanic ash and tuff layers from different volcanoes or eruptive events is a challenging task. In this study, samples of volcanic ash from the 2010 eruption of Bromo-a relatively young and active tuff cone volcano within the Sandsea caldera in the Tengger volcanic complex in East Java, Indonesia-along with two older tuff layers from the same caldera (Widodaren tuff: 1.8 kyr and Segarawedi tuff: 33 kyr) were subjected to magnetic measurements, geochemical analyses, and petrographic analyses. The aim is to attempt to use magnetic characters as a fingerprint for volcanic ash and tuff layers. The results show that the samples had variations in grain size and magnetic domain as indicated by the hysteresis parameters. These magnetic characters correlated with the results of geochemical and petrographic analyses, suggesting that magnetic properties may potentially be used as fingerprints to identify volcanic ashes and tuff layers.

Ash and gas discharge during open vent activity at El Reventador (Ecuador): explosion-style transitions driven by conduit capping

et al. 2022

Since the VEI 4 eruption of November 2002, El Reventador volcano (Ecuador) has been the site of persistent open-vent activity characterized by frequent (hourly) Vulcanian -Strombolian explosions and occasional (every few years) effusion of lava flows. The conduit processes that sustain this continuous eruptive activity are still poorly understood. Here we combine high temporal resolution thermal infrared imaging with seismic recordings and DOAS-derived SO2 fluxes focusing on a period of Vulcanian-style activity on 22-23 February 2017. Thermal imagery captured the emission and ascent dynamics of 26 plumes during the observation period, including those fed by explosions and degassing episodes. While most explosions have associated seismic signals, a few are marked by the absence of measurable seismic activity. Degassing episodes also show very few associated seismic signals. Explosions and degassing events seem to follow a sequence that can be explained by changes in the conduit permeability associated with rapid (over time scales of minutes) rheological stiffening of magma in the uppermost portion of the conduit to reduce degassing efficiency. Periods of open-vent outgassing alternate with periods of conduit capping resulting in system pressurization and leading to Vulcanian explosions that re-open the conduit allowing outgassing to resume.
